I have a site http://geraldberreman.com that has over 1000 images (and a lot more to come. It is the site of an anthropologist so the ability to search for images (children, mountains, etc) is essential. Since NextGEN has upgraded the "search" feature no longer works. I think the problem is related to the NextGEN Search Engine plugin by Alex Rabe needing to be updated. When I now do a search here is the error I"m getting: Fatal error: Call to undefined function nggcreategallery() in /home3/dandylew/public_html/zzgeraldberreman.com/wp-content/plugins/nggSearch/nggSearch.php on line 64
I sure hope this can be fixed... It's essential on a site like this to be able to search all photo data.

@Darrilyn - Yes, the plugin by Alex Rabe does need to be updated to work with the current version of NextGEN Gallery ... and unfortunately I was not able to re-create an issue where the plugin caused a fatal error on my test site.

... and if it is vitally important for you to have that functionality now, above and beyond all of the additional features the current NextGEN Gallery offers then this article on how to roll back to a NextGEN Legacy version may be helpful: http://www.nextgen-gallery.com/how-to-rollback-a-version/

I have migrated my http://geraldberreman.com website back to an august 2013 backup. This is the last backup I have where my Nextgen Search plugin worked. Once the Nextgen Gallery was updated to 2.+ versions the Nextgen Search Engine plugin no longer worked.
Here are the specifics of versions that would search photos:
Nextgen Gallery ver - 1.9.13
Nextgen Search Engine ver - 0.7.01

If you'd like to test how the site works: http://geraldberreman.com website try entering some words like:
mountains, Nepal, children, Sarona

This is the site I've created for a well known Anthropologist. We are archiving all his work and it's essential that we can search for photos.
the new versions of Nextgen somehow do not allow this to happen. Hopefully this can be a feature added soon.

I'd thing the ability to search photos themes and words on a website would be essential.

FYI, Nextgen Gallery no longer advises rolling back to version 1.9.13. From their blog: IMPORTANT NOTE! Rolling back to 1.9.13 is no longer supported and is likely to cause problems. Rollbacks should be limited to recent versions within the last couple months. Also, for anyone using Pro, any rollback should be limited to the minimum compatible version of NextGEN Gallery (v2.0.63).

I too am looking for a search engine that works with the new version of Nextgen Gallery.

NextGEN Gallery still has the NextGEN Search Engine by Alex Rabe on their list of recommended extension plugins. They should probably remove that one from the list, since it doesn't work with the new version of NextGEN Gallery.

@joyfulcartoonist - Thanks for the suggestion, we are updating documentation on our site and that list will be heavily reviewed (and most likely severely edited) once it reaches the front of the queue.
